atent No. 742,543, dated October 2'7, 1903.

Application filed September 16, 1902. Serial No. 123,621. (No model.)

To aZZ whom it may concern:

Be it known that we, THQMAsWILsON and Vroroa H. SLINAOK, citizens ofthe-United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvemen ts in Welsbach or other Burners, of which thefollowing is a specification.

The object of the invention is to fill a recog- 1O nized want and toprovide means to exclude bugs and insects from Welsbach and otherstreet-lights. Such bugs and insects have heretofore found a readypassage through the air-openings of the Bunsen tube, and their I5charred remains have clogged the burnercap and also left dull spots onthe incandescent or mantle, whereby great deterioration in the light hasresulted.

The invention consists in the improvements 2o hereinafter described andclaimed.

The nature, characteristic features, and scope of the invention will bemore fully understood from the following description, taken inconnection with the accompanying drawings, forming a part hereof,wherein- Figure 1 is a sectional elevational View of a Welsbachstreet-light having means for excluding bugs and insects in accordancewith this our present invention. Fig. 2 is an elevational view of amodification. Fig. 3 is a similar view of a modification. Fig. 4 is anelevational view showing the invention applied to a vapor-burner; andFig. 5 is a view of the same, on a smaller scale, showing the 5 guard orcasing opened.

Referring to Fig. 1, a represents a Bunsen tube equipped with anair-shutter b, needlevalve 0, yoke-support d, and burner-head 6, all ofthe usual and well-known construction.

0 There is also a gallery f. 9 represents an insect-guard consisting ofa reticulated member of substantially cylindrical or tubular form, so asto entirely surround the Bunsen tube. Such guard or casing may be madeof screen- 5 wire or its equivalent. The bottom of the guard rests onthe flange or collar 1) of the air-shutter, and the top is closed by theupper ringf of the gall the bottom of the air-shut ery. h is an outerinsect guard or casing, which is preferably carried by the gallery-ringf said ring also acting to close the space at the top between thetwo'insect-guards. The bottom of the outer casing or guard rests upon asheet metal washer or base-support i, interposed between ter and theyoke d.

In Fig. 2 use is made simply of the outer guard h, which is closed atits top by the cone or galleryj and at its bottom by the sheetmetalwasher or collar 7;.

In Fig. 3 the outer guard or casing his dispensed with; but otherwisethe construction is the same as that'illustrated in Fig. 1.

Referring to Figs. 4 and 5, 0. represents a well known construction ofvapor burner equipped with a needle-valve c and with an oil-supply pipe75. The bottom of the burnercasing is inclosed by a reticulated casingor insect-guard l, which is made to open, so that access. can be had tothe needle-valve 0. Such casing or guard may consist of the stationarypart or frame Z, suitably attached to the burner-casing, and a hingedpart or doorframe Z a suitable catch m being provided to maintain saiddoor closed. n represents screen -.wire or its equivalent fitted in thepartible frame or casing and through which air is supplied to theburner. The stationary part Z is perforated at top and bottom to permitthe passage of the oil-supply pipe is.

In Figs. 1 to 3 the insect-guards may be removed by simply removing thegalleries, the

uards being detachable therewith.

It will be obvious to those skilled in the art to which the inventionrelates that modifications maybe made in details without departing fromthe spirit and scope of same. Hence we do not limit ourselves to theprecise construction and arrangement of parts hereinbefore described,and illustrated in the accompanying drawings; but 90 Having describedthe nature and objects of the invention, what is claimed as new, anddesired to scour In combination, a Buns eby Letters Patent, is-

en burner, a gallery mounted in detachable relation therewith, and apair of screens carried by said gallery, whereof one extends from theinner or top ring of the gallery to below the air-inlet open-.

ings of the Bunsen, and whereof the other depends from the outer orbottom ring of the gallery, substantially as described.

In testimony whereof we have hereunto signed our names in the presenceof two subscribing witnesses.
